  • There seems to be a lot of misconceptions in the music community regarding the differences between 320kbps mp3 and FLAC format. It is true that 320kbps is technically as good as FLAC, but there are other reasons to get music in a lossless format.

    Hearing the difference now isn’t the reason to encode to FLAC. FLAC uses lossless compression, while MP3 is ‘lossy’. What this means is that for each year the MP3 sits on your hard drive, it will lose roughly 12kbps, assuming you have SATA – it’s about 15kbps on IDE, but only 7kbps on SCSI, due to rotational velocidensity. You don’t want to know how much worse it is on CD-ROM or other optical media.

    I started collecting MP3s in about 2001, and if I try to play any of the tracks I downloaded back then, even the stuff I grabbed at 320kbps, they just sound like crap. The bass is terrible, the midrange…well don’t get me started. Some of those albums have degraded down to 32 or even 16kbps. FLAC rips from the same period still sound great, even if they weren’t stored correctly, in a cool, dry place. Seriously, stick to FLAC, you may not be able to hear the difference now, but in a year or two, you’ll be glad you did.

    • Unfortunately, it seems you have a really bad misconception as well.

      Sorry, no, files (be it MP3 or FLAC or MP4 or whatever) do not degrade over time. Not one bit. Yes, storage devices do degrade and ultimately break down, but that does not result in MP3 files "losing 7 to 15 kbps per year". Digital files are like that—digital. They don't suffer the same degradation like vinyl where each playback damages the grooves and looses definition. Digital files are a bunch of zeros and ones (be it MP3 or FLAC or whatever) and it's either those bunch of numbers makes sense to the player (as in, it plays) or not (as in, the player shows an error saying it can't play the file).

      What you have experienced as "degradation" probably isn't the result of files degrading over the years. See, when MP3 was invented, the early encoders produced relatively bad sound quality for a given bitrate. They just can't pack that much information into 128kbps without affecting the sound quality. Over the years, many countless improvements were made to MP3 compression technology, and modern software like LAME can produce really good sound quality even at relatively low bitrates. That makes old files encoded using old encoders sound worse than new files encoded using new encoders at the same bitrate.

      MP3 doesn't even support 16kbps, so I can't imagine your storage device delicately removing bits from your MP3 files to reduce the bitrate without corrupting them, since storage devices can't even see the boundary between files—it only sees all the files as one huge string of numbers without any sense. Also, I can imagine your MP3 file shrinking in size every year if they do lose bits over time. Many filesystems also offer integrity checks on files, so your computer will alert you if something unintentional changes on your storage. Even some Linux filesystems will show an error if a single bit unexpectedly changes on one of your files.

      Wherever you read that misconception, please don't believe it. Digital files are not affected by quality degradation, and it's either they play, or they don't play.

      Hopefully you take this as a friendly message, and if this has been a joke and I've been whooshed, then you had me very well.

      • I can't tell if I'm being double-whooshed, but 'rotational velocidensity' is a very old meme. Your post is fully correct though, so good job!

        • Yeah, looking back, I've probably been whooshed, but I'd be very happy if I can at least help prevent someone from unknowingly falling for it. I'm a software developer as a profession, and I can't take false misunderstandings about digital stuff like this. Also as a digital audio enthusiast, I understand that digital audio is superior in every way at least theoretically but I also accept that some analog formats (like vinyl) have better mastering and can sound better than their CD re-releases.

          Peace!

        • I think it is just a joke, because of course IDE is still better in quality Preserving than Sata.

          • Make sure to only transfer MP3 files to your memory card using the serial port—USB degrades the sound quality by around 12 kbps per transfer /s

    • Had me in the first... third.

    • Should have stored them in the freezer. That's what I did, and I can still enjoy my 128kbps weird al mp3s from before y2k. Had a backup on CD in my attic, and tried it recently just for kicks... got an earful of actual mud. Took me a couple hours to get it all out of there with windex and qtips, but at least I can hear again.

    • Sorry man, they're too young to get it
